Land seismic data acquisition in most of cases suffers from obstacles in fields which deviates geometry of the real acquired data from what was designed. These obstacles will cause gaps, narrow azimuth and offset limitation in the data. These shortcomings, not only prevents regular trace distribution in bins, but also distorts the subsurface image by reducing illumination of the target formatio...

This phenomenon, studied since at least Perlmutter (1968), has been subject to two broad types of analysis (see Pesetsky (forthcoming)). In one, the effect derives from constraints on the whdependency related to the hierarchical structure of the sentence, while in the other, it derives from constraints on the linear order of elements. In the latter type of analysis, some have argued that the co...

preventive maintenance scheduling is to perform a series of tasks that prevents or minimizes production breakdowns and improves the reliability. mathematical models have been developed to solve the preventive maintenance scheduling problem. there are several limitations in the prior work in this area of research. craft combinations are assumed to be given. the craft combination problem concerns...

We derive results on equivalence of piecewise polynomial approximations a given function in the Sobolev space $${\varvec{H}}{\mathrm{(curl)}}$$ . namely show that global-best approximation -conforming imposing continuity tangential trace can be bounded above and below by Hilbertian sum respective local from elementwise spaces without any inter-element requirement. In other words, tangential-tra...

this study focuses on jane austens representation of her heroines in two of her novels: pride and prejudice, and mansfield park. i have concentrated only on a single idea: how jane austen takes her heroines through a course of psychogical reformation to which almost everything else in her novel is subsidiary. although i have discussed only pride and prejudice, we can trace austens carefully pla...

این رساله را با مفاهیم و قضایای اساسی آغاز می کنیم. سپس عملگر اسکتن و trace class را تعریف می کنیم و نشان می دهیم یک جبرژردان از عملگرهای شبه پوچ توان و فشرده شامل عملگر trace class ، زیرفضای پایا دارد. هم چنین نشان می دهیم یک جبر ژردان از عملگرهای شبه پوچ توان اسکتن مثلثی شونده است. در نهایت به بررسی ویژگی های عملگرهای کراندار که در شرایط طیفی جمعی و ضربی صدق می کنند می پردازیم و نتایج آنها را...

in this paper, the effect of financial liberalization on household’s budget liquidity constraint is analyzed with the use of an error correction model. financial liberalization will decline liquidity constraint, with expanding means of making future incomes available for present consumption. here a financial liberalization index for iran is defined using principal component analysis technique, ...

Inversion of magnetic data is an important step towards interpretation of the practical data. Smooth inversion is a common technique for the inversion of data. Physical bound constraint can improve the solution to the magnetic inverse problem. However, how to introduce the bound constraint into the inversion procedure is important. Imposing bound constraint makes the magnetic data inversion a n...
